Not really. I'm sure it's there, but it's quite small.
I just shaved the same way I do with a full DE blade, and it worked just the same.
Now in a Fatboy, yes there was a big difference in blade angle, at both 1 and 9 adjustment settings. The difference was noticeable enough that I didn't feel comfortable trying to shave with it.
As for the danger, I think T Rick nailed it. I'm most worried about having to cut blades in half and position the 1/2 blades when changing them. It's sorta tricky. As near as I can tell, once a 1/2 blade is loaded into the SS, it's about as safe to use as a full blade. (That's not the case in all razors though!) But there's no harm in assuming I'm wrong there, it's been known to happen

.
If the silo doors get loose, the 1/2 blade has a dangerous amount of play … but so does a full blade. The "bar" in the middle of the razor, and the hinges on the doors keep the 1/2 blade from sliding out, until the doors are opened pretty far.
I can't see any reason not to be more careful though. It's quite possible that something about having only 1/2 a blade makes silo doors more prone to open. Everything stayed tight for me, but yeah, I've only tried once so far.
